Description

Technical Field

[0001] The utility model relates to a cooking utensil. Background Art

[0002] Most current cooking appliances use a single inner pot design, which allows only one cooking condition at a time. Users who need to cook food at different conditions must use multiple cooking utensils. Existing dual-pot cooking appliances, including pressure cookers, often require two inner pots to accommodate different cooking pressures, as the two pots have different requirements for the center plate.

[0003] Therefore, it is necessary to provide a cooking appliance to at least partially solve the above problems. Utility Model Content

[0004] The Summary of the Utility Model introduces a series of simplified concepts that will be further described in the Detailed Description of the Utility Model. The Summary of the Utility Model of the Utility Model does not intend to limit the key features and essential technical features of the claimed technical solution, nor does it intend to determine the scope of protection of the claimed technical solution.

[0005] In order to at least partially solve the above problems, the present invention provides a cooking utensil, comprising:

[0006] A pot body, wherein two pot inner parts are provided in the pot body;

[0007] a cover body, the cover body being openably and closably arranged on the pot body, and a cooking space being formed between the cover body and the pot body;

[0008] a middle plate, the middle plate being located at the upper end of the pot body, the middle plate having a first opening, a first mounting portion extending circumferentially around the first opening, a second opening, and a second mounting portion extending circumferentially around the second opening, the second mounting portion having a mounting groove opening radially inward;

[0009] a first heat-insulating cover, wherein the first heat-insulating cover is located in the first opening, and a top edge of the first heat-insulating cover extends radially outward to form a first edge, and at least a portion of the first edge is located above the first mounting portion; and

[0010] A second heat-insulating cover, wherein the second heat-insulating cover is located in the second opening, and the top edge of the second heat-insulating cover extends radially outward to form a second edge, and at least a portion of the second edge is located in the mounting groove; wherein,

[0011] The two inner pots are respectively arranged corresponding to the first heat-insulating cover and the second heat-insulating cover.

[0012] According to this solution, by coordinating the first mounting portion with the first thermal insulation cover, the edge of the first thermal insulation cover is placed above the first mounting portion, and with the support of the middle plate, the first thermal insulation cover can safely withstand the internal high pressure generated during the cooking process, ensuring the safety and reliability of the cooking process. Through the setting of the mounting groove of the second mounting portion, part of the edge of the second thermal insulation cover can be directly embedded in the mounting groove, which not only simplifies the installation process, but also reduces the need for additional connectors and fixings, further reducing costs. At the same time, the second edge can be set at a lower height, saving the material cost of the second thermal insulation cover. In this solution, the first thermal insulation cover and the second thermal insulation cover can share a middle plate, which not only improves the overall structural compactness of the cooking utensil, but also optimizes the manufacturing cost and user experience.

[0013] Optionally, the first mounting portion includes a first connecting rib connected to the middle plate body, a first convex rib extending radially inward along the first connecting rib, a second convex rib extending circumferentially upward along the first connecting rib, and a third convex rib extending circumferentially downward along the first connecting rib; wherein,

[0014] The second rib is used to support the first edge.

[0015] According to this solution, the coordinated arrangement of the first connecting rib, the first convex rib, the second convex rib and the third convex rib constitutes a stable mounting structure for the first heat-insulating cover, thereby ensuring the stability and reliability of the entire structure.

[0016] Optionally, part of the first connecting ribs and the first convex ribs are arranged opposite to each other in the radial direction, and part of the first connecting ribs and the first convex ribs are staggered in the radial direction; and / or

[0017] Part of the first convex rib and the second convex rib are arranged opposite to each other along the height direction, and part of the first convex rib and the second convex rib are staggered along the height direction.

[0018] According to this solution, by staggering the arrangement, the first connecting rib, the first convex rib, the second convex rib and the third convex rib are bent in the center area of ​​the cross to disperse stress, enhance the overall rigidity and anti-deformation ability, and thus enhance the supporting force of the second convex rib.

[0019] Optionally, the thickness of the first connecting rib is greater than the thickness of the first convex rib, and the thickness of the first connecting rib is greater than the thickness of the third convex rib; and / or

[0020] The thickness of the second convex rib is greater than the thickness of the first convex rib, and the thickness of the first convex rib is greater than the thickness of the third convex rib.

[0021] According to this solution, appropriately increasing the thickness of the first connecting rib and the second convex rib can ensure the stability and reliability of the connection and provide higher supporting force; while ensuring sufficient strength, appropriately reducing the thickness of the first convex rib and the third convex rib can help reduce material costs and reduce overall weight.

[0022] Optionally, the upper surface of the first connecting rib is inclined from top to bottom in a direction away from the first heat-insulating cover.

[0023] According to this solution, the first connecting rib is inclined toward the middle plate body with a lower height. When the soup in the pot overflows, the water will not flow into the first insulation cover from the gap between the middle plate and the first pot body, reducing the risk of short circuit in the bottom circuit.

[0024] Optionally, the second mounting portion includes a second connecting rib connected to the middle plate body, a fourth rib connected to the second connecting rib and extending radially inward, and a fifth rib extending circumferentially downward along the second connecting rib; wherein,

[0025] The fourth rib forms the mounting groove, and the fourth rib is used to support the second edge.

[0026] According to this solution, the mounting groove can support and position the second edge, and the fifth rib extends circumferentially downward along the second connecting rib, thereby reinforcing the second mounting portion as a whole and further improving the stability of the structure.

[0027] Optionally, the fourth convex rib includes a first sub-rib and a second sub-rib that are spaced apart and arranged opposite to each other along the height direction, and the second edge is clamped between the first sub-rib and the second sub-rib.

[0028] According to this solution, the arrangement of the first and second sub-ribs provides stable support and positioning for the second edge, thereby preventing it from shaking or falling off during the cooking process.

[0029] Optionally, the upper surface of the fourth rib is higher than the upper surface of the middle plate body; and / or

[0030] The upper surface of the second connecting rib is inclined from top to bottom in a direction away from the second heat-insulating cover.

[0031] According to this solution, the second connecting rib is inclined toward the middle plate body with a lower height. When the soup in the pot overflows, the water will not flow into the second insulation cover from the gap between the middle plate and the second pot body, reducing the risk of short circuit in the bottom circuit.

[0032] Optionally, a plurality of the fourth ribs are arranged in an array and at intervals along the circumference of the second connecting rib, and the second edge is arranged corresponding to the fourth ribs.

[0033] According to this solution, by pairing the plurality of fourth ribs with the plurality of second edges, the installation and removal processes of the second heat-insulating cover are made smoother and more convenient while ensuring the connection strength.

[0034] Optionally, the thickness of the fifth rib is greater than the thickness of the fourth rib.

[0035] According to this solution, the fourth rib serves as the main load-bearing component for the second heat-insulating cover, and the fifth rib connected thereto is close to the horizontal plane of the middle plate. Therefore, appropriately increasing the thickness of the fifth rib can ensure the supporting strength for the second heat-insulating cover.

[0036] Optionally, the middle plate is provided with support columns, and at least two of the support columns are located between the first opening and the second opening.

[0037] According to this solution, a support portion is provided between the first opening and the second opening to prevent the middle of the middle plate from being crushed by the heat-insulating cover and the pot body on both sides, thereby being able to better bear the load.

[0076] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with embodiments of the present invention.

[0077] In this document, ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component".

[0078] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0079] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0080] Unless otherwise stated, numerical ranges herein include not only the entire range between its two endpoints but also the several sub-ranges contained therein.

[0081] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0082] The present invention provides a cooking appliance. The dual-pot configuration of the cooking appliance allows the user to perform multiple cooking operations simultaneously, improving cooking efficiency and shortening cooking time. The cooking appliance can function as an electric rice cooker and / or an electric pressure cooker to meet diverse cooking needs. In addition to cooking rice, it can also be used for cooking porridge, soup, steaming vegetables, stewing meat, and other various other functions.

[0083] The following will be combined Figures 1 to 8 The cooking appliance according to the present invention is described in detail.

[0084] like Figure 1-Figure 2As shown, the cooking appliance primarily comprises a pot body 100 and a lid 200, which is arranged to open and close above the pot body 100. The pot body 100 has two cylindrical pot storage compartments. The pot is fixedly mounted in the pot storage compartments, or it can be freely inserted and removed from the pot storage compartments for easy cleaning. The pot is typically made of metal and has a circular opening on its top surface for holding ingredients to be heated, such as rice or soup. The pot body 100 also includes a pot heating device and a control device. The pot heating device can be located at the bottom of the pot to heat the food inside, and the user can control the cooking operation of the cooking appliance through the control device. Optionally, the pot heating device can be configured as two independent heater components, one for each pot. The two heaters can operate independently or simultaneously, allowing the double pot cooking appliance to perform two or the same cooking functions.

[0085] The pot body 100 may include a housing 110 and a base 120 located at the lower side of the housing 110. The lower end of the housing 110 may be connected to the base 120 by any suitable means such as snap connection, plug connection, or fastening connection with fasteners such as screws.

[0086] Optionally, a middle plate 400 is provided at the upper end of the pot body 100. Specifically, the middle plate 400 is connected to the upper end of the outer shell 110. The upper end of the outer shell 110 can be connected to the middle plate 400 by any suitable means, such as snap-fitting, plug-in connection, or fastening with fasteners such as screws. Optionally, the middle plate 400 and the base 120 can be connected. For example, the middle plate 400 can be provided with a downwardly extending support column 430, and the base 120 can be provided with an upwardly extending hollow screw column. The screw can be inserted from the underside of the screw column and partially exit from the top of the screw column to be tightened to the support column 430.

[0087] The lid 200 has a shape substantially corresponding to the pot body 100. Accordingly, two lids 200 are provided corresponding to the two inner pots. The lid 200 is mounted on the pot body 100 in an openable and closable manner. Specifically, it is pivotally connected to the pot body 100 via a pivot shaft and can freely pivot about a pivot axis located along which the pivot shaft lies between a closed position and an open position relative to the pot body 100, facilitating closing and opening of the pot body 100. When the lid 200 is closed on the pot body 100, it covers the inner pot body and defines a cooking space between the inner pot body and the inner pot body. Optionally, the two lids 200 can be opened and closed independently, or they can be integrated and opened and closed simultaneously. The lid 200 also typically includes a pot mouth sealing ring 210, which can be made of, for example, a rubber material. The pot mouth sealing ring 210 is positioned between the lid 200 and the inner pot body to seal the cooking space when the lid 200 is closed. It can be understood that when the two covers 200 are combined with the two pot cores, two independent and relatively sealed cooking spaces are formed.

[0088] It should be noted that directional terms used herein to describe various components and parts of the pot body 100, such as "up," "down," "above," "below," "upward," "downward," "upward," and "downward," are relative to the pot body 100 when it is horizontally placed and upright. Unless otherwise specified, in the directional terms "inward," "outward," "inwardly," "outwardly," "inside," and "outside," "inside," and "outside," "inside" refers to a direction closer to the center of the pot body 100, and "outside" refers to a direction further away from the center of the pot body 100.

[0089] like Figure 3-Figure 6 As shown, the middle plate 400 has a first opening 401, a first mounting portion 410 extending circumferentially around the first opening 401, a second opening 402, and a second mounting portion 420 extending circumferentially around the second opening 402. Thus, the middle plate 400 forms a structure suitable for mounting two inner pots. The inner pots include a first inner pot 310 and a second inner pot 320.

[0090] The first pot 310 provided by the present invention is suitable for pressure cooking, and the second pot 320 is suitable for normal pressure cooking.

[0091] In this embodiment, to reduce heat loss during cooking and prevent the two inner pots from interfering with each other during cooking, a heat shield is provided around the periphery of each inner pot. Optionally, the heat shield is connected to the middle plate 400. Optionally, the middle plate 400 provides direct support for the heat shield.

[0092] The heat preservation cover includes a first heat preservation cover 510 and a second heat preservation cover 520. The first heat preservation cover 510 and the second heat preservation cover 520 can share a middle plate 400, which not only improves the overall structural compactness of the cooking utensil, but also optimizes manufacturing costs and user experience.

[0093] The first heat-insulating cover 510 is located in the first opening 401. That is, the first heat-insulating cover 510 is installed to the pot body 100 via the first opening 401. The top edge of the first heat-insulating cover 510 extends radially outward to form a first edge 511, and at least part of the first edge 511 is located above the first mounting portion 410. Optionally, the first heat-insulating cover 510 is used to install the first pot inner body 310. The first pot inner body 310 is suitable for pressure cooking. In order to meet the requirements of pressure cooking, the first heat-insulating cover 510 usually needs to cooperate with the hardware of the cover body 200 to withstand internal pressure. In the present utility model, the first heat-insulating cover 510 is arranged above the middle plate 400. Specifically, the edge of the first heat-insulating cover 510 is located above the first mounting portion 410. Under the premise of ensuring the connection strength of the first heat-insulating cover 510, sufficient support force is provided for the first heat-insulating cover 510, which is crucial for withstanding the internal pressure generated during pressure cooking, ensuring the safety and reliability of the pressure cooking process.

[0094] The second heat-insulating cover 520 is located within the second opening 402. That is, the second heat-insulating cover 520 is mounted to the pot body 100 via the second opening 402. The top edge of the second heat-insulating cover 520 extends radially outward to form a second edge 521, which is connected to the second mounting portion 420. Optionally, the second heat-insulating cover 520 is used to mount the second pot 320. The second pot 320 is suitable for normal pressure cooking. During normal pressure cooking, the second heat-insulating cover 520 does not need to be aligned with the second pot 320, and the pressure during normal pressure cooking is generally lower than that during pressure cooking (specifically, high-pressure cooking). In the present invention, to save costs, the second heat-insulating cover 520 can be positioned below the plane. Specifically, the second mounting portion 420 has a mounting groove 4220, with at least a portion of the second edge 521 located within the mounting groove 4220. The force bearing point of the second heat-insulating cover 520 is located within the mounting groove 4220, that is, at the lower portion of the upper surface of the middle plate 400.

[0095] As can be seen above, the first heat-insulating cover 510 is used to mount the first inner pot 310. The second heat-insulating cover 520 is used to mount the second inner pot 320. Thus, the inner pot storage portion of the pot body 100 is formed within the heat-insulating cover, allowing the inner pot to be freely placed in and removed from the inner pot storage portion. In other embodiments, the inner pot can be fixed within the inner pot storage portion.

[0096] Thus, by coordinating the first mounting portion 410 with the first heat-insulating cover 510, the edge of the first heat-insulating cover 510 is positioned above the first mounting portion 410. Leveraging the support provided by the middle plate 400, the first heat-insulating cover 510 can safely withstand the internal high pressure generated during cooking, ensuring the safety and reliability of the cooking process. The second mounting portion 420, through the provision of the mounting groove 4220, allows a portion of the edge of the second heat-insulating cover 520 to be directly embedded within the mounting groove 4220, simplifying the installation process and reducing the need for additional connectors and fixtures, further reducing costs. Furthermore, the second edge 521 can be positioned at a lower height, saving material costs for the second heat-insulating cover 520.

[0097] Reference Figure 3-Figure 7The first mounting portion 410 includes a first connecting rib 411 connected to the middle plate 400 body, a first rib 412 extending radially inward along the first connecting rib 411, a second rib 413 extending circumferentially upward along the first connecting rib 411, and a third rib 414 extending circumferentially downward along the first connecting rib 411. The second rib 413 is used to support the first edge 511. The first connecting rib 411 securely connects the first mounting portion 410 to the middle plate 400 body, forming a stable mounting structure for the first heat-insulating cover 510 and ensuring the stability and reliability of the entire structure. The second rib 413 extends circumferentially upward along the first connecting rib 411, directly supporting the first edge 511 of the first heat-insulating cover 510 and ensuring the stability and safety of the first heat-insulating cover 510 and the first inner pot 310 during cooking. The first rib 412 extends radially inward along the first connecting rib 411 and supports the first inner pot 310 radially, preventing it from loosening or shifting during cooking. The third rib 414 extends circumferentially downward along the first connecting rib 411, reinforcing the first connecting portion circumferentially. The first rib 412 and the third rib 414 simultaneously serve to locate the center of the circle.

[0098] Optionally, part of the first connecting ribs 411 and the first convex ribs 412 are arranged opposite to each other in the radial direction, and part of the first connecting ribs 411 and the first convex ribs 412 are staggered in the radial direction.

[0099] Optionally, part of the first convex rib 412 and the second convex rib 413 are arranged opposite to each other along the height direction DH, and part of the first convex rib 412 and the second convex rib 413 are staggered along the height direction DH.

[0100] Through the above-mentioned partial staggered arrangement, the first connecting rib 411, the first convex rib 412, the second convex rib 413 and the third convex rib 414 are bent in the center area of ​​the cross to disperse stress, enhance the overall rigidity and anti-deformation ability, and thus enhance the supporting force of the second convex rib 413.

[0101] Optionally, the thickness of the first connecting rib 411 is greater than the thickness of the first convex rib 412 , and the thickness of the first connecting rib 411 is greater than the thickness of the third convex rib 414 .

[0102] Optionally, the thickness of the second rib 413 is greater than the thickness of the first rib 412 , and the thickness of the first rib 412 is greater than the thickness of the third rib 414 .

[0103] In the above embodiment, the first connecting rib 411, as the main connecting component, needs to withstand the weight of the first heat-insulating cover 510 (or the first pot core 310) and various forces during the cooking process. The second rib 413 directly supports the first edge 511 of the first heat-insulating cover 510 and is a key component to ensure the stability of the heat-insulating cover. Therefore, appropriately increasing the thickness of the first connecting rib 411 and the second rib 413 can ensure the stability and reliability of the connection and provide a higher supporting force. Although the first rib 412 and the third rib 414 also play a certain supporting and reinforcing role, the force they bear is smaller than that of the first connecting rib 411 and the second rib 413. Therefore, under the premise of ensuring sufficient strength, appropriately reducing its thickness can help reduce material costs and reduce overall weight.

[0104] Optionally, the upper surface of the first connecting rib 411 slopes downward, away from the first insulation cover 510. Specifically, the first connecting rib 411 slopes toward the lower middle plate 400. This prevents water from flowing into the first insulation cover 510 through the gap between the middle plate 400 and the first inner pot 310 when the pot overflows, reducing the risk of short circuits at the bottom. Optionally, the middle plate 400 is provided with a water collection box to collect overflowing water.

[0105] Reference Figure 3-Figure 6 and Figure 8 The second mounting portion 420 includes a second connecting rib 421 connected to the middle plate 400 body, a fourth rib 422 connected to the second connecting rib and extending radially inward, and a fifth rib 423 extending circumferentially downward along the second connecting rib. The fourth rib 422 forms a mounting groove 4220, which is used to support the second edge 521. The second connecting rib 421 firmly connects the second mounting portion 420 to the middle plate 400 body, thereby forming a stable mounting structure for the second heat-insulating cover 520 and ensuring the stability and reliability of the entire structure. The fourth rib 422 extends radially inward to form a mounting groove 4220 for supporting and positioning the second edge 521 of the second heat-insulating cover 520, ensuring the stability and positional accuracy of the second mounting portion 420 during the cooking process. The fifth rib 423 extends circumferentially downward along the second connecting rib 421, reinforcing the second mounting portion 420 as a whole and further improving the stability of the structure.

[0106] In some embodiments, the upper end of the mounting groove 4220 is not closed, that is, the mounting groove 4220 has a bottom wall and side walls, and the second edge 521 overlaps the bottom wall. In other embodiments, the upper end of the mounting groove 4220 is closed, that is, the mounting groove 4220 has a top wall, a bottom wall, and side walls, and the second edge 521 can be screwed into the side of the mounting groove 4220 to overlap the bottom wall of the mounting groove 4220.

[0107] Optionally, the fourth rib 422 includes a first sub-rib 4221 and a second sub-rib 4222 that are spaced apart and arranged opposite to each other along the height direction DH, and the second edge 521 is clamped between the first sub-rib 4221 and the second sub-rib 4222. That is, the first sub-rib 4221 and the second sub-rib 4222 constitute the groove wall of the mounting groove 4220. Optionally, the first sub-rib 4221 is connected to the upper portion of the second connecting rib, and the second sub-rib 4222 is connected to the lower portion of the second connecting rib. The height and shape of the mounting groove 4220 match the second edge 521, allowing the second edge 521 to be stably installed in the mounting groove 4220. The double-layer groove wall structure provides stable support and positioning for the second edge 521, preventing it from shaking or falling off during the cooking process. When installing the second heat preservation cover 520, the user only needs to align the second edge 521 and snap it into the mounting groove 4220 to complete the installation.

[0108] Reference Figure 4 The upper surface of the fourth rib 422 is higher than the upper surface of the middle plate 400. Optionally, the upper surface of the second connecting rib 421 slopes downward, away from the second insulation cover 520. Specifically, the second connecting rib 421 slopes toward the lower middle plate 400. This prevents water from flowing into the second insulation cover 520 through the gap between the middle plate 400 and the second inner pot 320 when the pot overflows, reducing the risk of short circuits at the bottom.

[0109] Optionally, the fourth ribs 422 may be provided continuously or at intervals.

[0110] Reference Figure 5-Figure 6 Multiple fourth ribs 422 are arranged in an array and spaced apart circumferentially around the second connecting rib 421. That is, multiple mounting grooves 4220 are circumferentially arranged. Second edges 521 are arranged corresponding to the fourth ribs 422. In other words, the second edges 521 are configured as circumferentially spaced tooth-like structures. The paired arrangement of multiple fourth ribs 422 and multiple second edges 521 ensures connection strength while making installation and removal of the second thermal insulation cover 520 smoother and more convenient.

[0111] In the above embodiment, the fourth rib 422 serves as the main load-bearing component for the second thermal insulation cover 520, and the fifth rib 423 connected thereto is close to the horizontal plane of the middle plate 400. Therefore, appropriately increasing the thickness of the fifth rib 423 can ensure the supporting strength of the second thermal insulation cover 520.

[0112] In some embodiments of the present invention, at least two support columns 430 are located between the first opening 401 and the second opening 402. A support portion is provided between the first opening 401 and the second opening 402 to prevent the middle of the middle plate 400 from being crushed by the heat insulation cover and the pot body on both sides, thereby being able to better bear the load. Figure 5 and Figure 6Two support columns 430 are located between the first opening 401 and the second opening 402, two support columns 430 are located on the left side of the first opening 401, and two support columns 430 are located on the right side of the second opening 402. By setting up multiple support columns 430, the middle plate 400 is subjected to uniform force.

[0113] In the present invention, the middle plate 400 can be made of plastic. The middle plate 400 and the first connecting rib 411, first convex rib 412, second convex rib 413, third convex rib 414, second connecting rib 421, fourth convex rib 422, fifth convex rib 423, and support column 430 disposed thereon can be made of the same material as the middle plate 400, for example, by injection molding.
